Does the soup in braised vegetables restaurants never change?

Don’t talk nonsense if you don’t understand. The longer the braised soup is, the better it tastes. Boil it once a day in summer and once every two days in winter. You have to cook something every day. Even if you don’t cook, you have to boil the pot, so it won’t go bad at all. , the stewed soup in my store has been around for many years. It was more than seventy years old when I got it. I have been using it for three or four years.
